Support for what you're doing is rather thin on the ground..

You'd want to make sure you have IRQHandlers correctly calling into the HAL, and ensure that none of the calls you are making return errors or block.

Hi, i solve the problem

just add 4 line in start of program:

__HAL_UART_ENABLE_IT(&huart8,UART_IT_RXNE);

__HAL_UART_ENABLE_IT(&huart8,UART_IT_TC); __HAL_UART_ENABLE_IT(&huart7,UART_IT_RXNE); __HAL_UART_ENABLE_IT(&huart7,UART_IT_TC);

when i use one uart i don't need this lines but when i use two uart, i need.

thanks.
